books by the same author, but different titles?
(A) Unlike APA where you would sort them by year (Johnson, 1991a) (Johnson, 1991b) (Johnson, 1991c), MLA states that, since you don’t use dates, you would add the first part of the title to the source. Example: (Johnson, “Study” 67-69). and (Johnson, Biology 45-50). Note: You use underline if it is a book being quoted, and you use quote marks if it is an article being quoted).
